why isn’t there a Subtract operator?
is there a prospect for using actual operators and actual literals here?
Thank you so much Matthew, Pradeep, and everyone else helping with this effort!_______________________________________________And thanks Matthew for sharing the slides — very informative! I’ve asked Sebastian for the recording but in the meantime I thought I’d ask a couple of questions about the syntax:* why isn’t there a Subtract operator? It seems that Subtract[A, B] is much more readable than Add[A, Multiply[Literal[-1], B]]?* is there a prospect for using actual operators and actual literals here? I think that a lot of reticence about Python typing comes from the annotations being so difficult to read. There’s been some great improvements recently with “Optional[Tuple[Union[Float, Int]]]” becoming “tuple[float | int] | None”, and I hope we can leapfrog the awkward phase with this tensor typing stuff. Again, A - B is much more readable again than Subtract[A, B]. And B-2 is much more readable than Add[B, Literal[-2]].Other than that, love the work, thank you again!Juan.On 11 Jun 2021, at 5:08 am, Matthew Rahtz <mrahtz@google.com> wrote:Some links I promised to send around:

We have made a recording, but I did not plan on making it available
publicly. Please contact me directly if you are interested.
Cheers,
